CVE-2026-32944 Details
Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.21 and 8.6.45, an unauthenticated attacker can crash the Parse Server process by sending a single request with deeply nested query condition operators. This terminates the server and denies service to all connected clients. Starting in version 9.6.0-alpha.21 and 8.6.45, a depth limit for query condition operator nesting has been added via the `requestComplexity.queryDepth` server option. The option is disabled by default to avoid a breaking change. To mitigate, upgrade and set the option to a value appropriate for your app. No known workarounds are available.
A denial-of-service vulnerability has been identified in Parse Server versions 9.0.0 prior to 9.6.0-alpha.21 and in versions prior to 8.6.45. The issue allows an unauthenticated attacker to crash the Parse Server process by sending a request with deeply nested query condition operators. This action terminates the server process, causing a service disruption for all connected clients.
To address this vulnerability, users should upgrade to Parse Server versions 9.6.0-alpha.21 or 8.6.45. After upgrading, the `requestComplexity.queryDepth` server option should be enabled and set to a value appropriate for the application.
